NOTICE
Safety Instructions for Machinery
SECTION 1: SAFETY
-8-
Model G0828/G0829 (Mfd. Since 02/17)
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica-
tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement dur-
ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec-
ommended accessories. Using improper acces-
sories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!
MAINTAIN POWER CORDS. When disconnect-
ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend-
ed operation, stop using the machine! Contact our

Additional Safety for Metal Shears
AMPUTATION HAZARD. The shear blades can
easily pinch, crush, or amputate fingers or other
body parts. Always keep hands, fingers, and other
body parts away from the blades during operation.
SHARP METAL EDGES. Sharp edges on newly
cut sheet metal workpieces can easily cause deep
cuts while handling. Wear leather gloves to help
protect your hands when handling workpieces, and
always chamfer and debur sharp workpiece edges.
PROPER WORKPIECE MATERIAL. This shear is
only intended for cutting ferrous and non-ferrous
sheet metal or flat stock. Do not attempt to cut
round metal stock, glass, wood, drywall, backer
board, plywood, or other material not intended for
this machine. Cutting incorrect materials can pro-
duce unexpected results, which increases the risk
of injury, and may result in damage to the machine.
SECURE SHEAR BEFORE USE. Before using,
fasten shear to a sturdy surface that can withstand
the dynamic forces involved in shearing sheet
metal. Otherwise, shear may unexpectedly move
or fall, causing serious injury or property damage.
STABLE FOOTING. This shear requires you to
apply a moderate/high level force while cutting.
Without stable footing, you could slip or fall, which
could cause personal injury. Always stand with
both feet comfortably on a non-slip surface during
operation.
BODY POSITION. The forces and body motion
required to operate this shear can result in opera-
tor injury over time if proper technique is not used.
Always keep your body centered with the machine
and your back straight when applying pressure
against handles.
BLADE CONDITION. Blades that are sharp,
undamaged, and properly adjusted will reduce risk
of injury and improve cutting results. Always keep
blades properly maintained.
BLADE GUARD. The blade guard is designed
to reduce risk of amputation. Always keep guard
properly attached and in good condition during
operation.
RATED CAPACITY. Only use sheet metal that is
within the rated capacity of this shear (refer to the
Machine Data Sheets on Page 5 and 6).
Like all machinery there is potential danger
when operating this machine. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, seri-
ous personal injury may occur.
No list of safety guidelines can be com-
plete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
this and other machinery with caution and
respect. Failure to do so could result in
serious personal injury, damage to equip-
ment, or poor work results.

The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
There are many ways to remove this rust preven-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac-
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
• Disposable rags
• Cleaner/degreaser (WD•40 works well)
• Safety glasses & disposable gloves
• Plastic paint scraper (optional)
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. Avoid
using these products
to clean machinery.
Many cleaning solvents
are toxic if inhaled. Only
work in a well-ventilated
area.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.
Cleanup
T23692—Orange Power Degreaser
A great product for removing the waxy shipping
grease from your machine during clean up.

Weight Load
Refer to the Machine Data Sheet
for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work-
piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
Physical Environment
The physical environment where the machine
is operated is important for safe operation and
longevity of components. For best results, oper-
ate this machine in a dry environment that is
free from excessive moisture, hazardous chemi-
cals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range is outside 41°–104°F; the relative humidity
range is outside 20–95% (non-condensing); or
the environment is subject to vibration, shocks,
or bumps.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main-
tenance and service described in this manual.
See below for required space allocation.

Lifting & Placing
HEAVY LIFT!
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,
get help from other people
and use a forklift (or other
lifting equipment) rated for
weight of this machine.
To lift and place shear on workbench:
1. Move shear to installation location while it is
still on shipping pallet.
2. To avoid damage from lifting straps, remove
M6-1 x 12 cap screws and 6mm flat washers
(14 on G0828, 16 on G0829) securing lower
cover, blade guard, and upper cover, (see
Figure 6).
7. Fasten shear to workbench as recommended
in Bench Mounting.
3. Remove fasteners securing shear to pallet.
Save hardware for mounting in Step 7.
4. Position straps under shear and attach to
forklift. Or, with help from others, lift shear
onto workbench and proceed to Step 6.
Bench Mounting
The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.
The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.

Leveling
Leveling the shear helps the blades and other
cast-iron components remain straight and flat
during the life of the machine. Components on
an unleveled machine may slowly twist over time
due to the dynamic loads placed on the machine
during operation. Twisted components will impair
the ability of the machine to cut straight or square.
If needed, use metal shims between the base and
the workbench to level the machine. Measure with
a precision level that is at least 12" long and sensi-
tive enough to show a distance movement when a
0.003" shim is placed under one end of the level.
3. Slide work stop adjustment assembly onto
support rods, as shown in Figure 11, with flat
side of L-bracket closest to shear. Tighten (4)
knurled thumbscrews.
Assembly
Assembly of the Model G0828/G0829 consists of

SECTION 3: OPERATIONS
Operation Overview
The purpose of this overview is to provide the nov-
ice machine operator with a basic understanding
of how the machine is used during operation, so
the
machine controls/components
discussed later
in this manual
are easier to understand.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual,
seek additional
training from experienced
machine operators
, and do additional research
outside of this manual by reading "how-to" books,
trade magazines, or websites.
To complete a typical operation, the operator
does the following:
1. Examines workpiece to make sure it is suit-
able for cutting.
2. Adjusts rear work stop for length of cut.
3. Puts on safety glasses, leather boots, and
leather gloves.
4. Places workpiece on bed and up against side
work stop.
5. Slides workpiece under blades and against
rear work stop.
6. Using good body position, firmly pulls down
on cutting lever to make cut.
7. Lifts cutting lever and removes workpiece or
repeats Steps 5–6 to make additional cuts.
To reduce your risk of
serious injury, read this
entire manual BEFORE
using machine.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any proj-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable
for accidents caused by lack of training.
Bodily injury could result from using this
machine. Always wear safety glasses,
leather work boots, and heavy duty leather
work gloves when operating this machine
or whenever handling sheet metal.
The shear blades or hold-
down can easily pinch,
crush, or amputate fingers
or other body parts. Always
keep hands, fingers, and
other body parts away from
the blades and hold-down
during operation.

Cutting Tips
• Keep the upper blade properly adjusted to
the lower blade (refer to Adjusting Blade
Gap on Page 24 for detailed instructions).
This will help ensure good cutting results and
avoid blade damage.
• Before each operation, clear cut-offs or debris
away from the shear.
• Make sure the 90° guide is square with the
blades (see Page 18). This will help ensure
the cut is square.
• Use the cutting lever to engage the hold-
down bar with the workpiece, then check the
workpiece position. If it is correct, continue
lowering the cutting lever to complete the cut.
• The shearing action of the blades works simi-
larly to a pair of scissors (see the illustration
in Figure 12). Use even pressure on the cut-
ting lever to produce good results.

Adjusting
Hold-Down Bar
The hold-down bar secures the workpiece to the
bed before the blades shear the workpiece.
The hold-down bar is adjustable for height. The
G0828 uses two adjustment hex bolts and hex
nuts (see Figure 13). The G0829 uses three
adjustment hex bolts and hex nuts.
Tools Needed Qty
Open-End Wrenches 18mm .............................. 2

Adjusting
Rear Work Stop
The rear work stop is used for making repetitive
cuts. The adjustable assemblies allow for precise
positioning of the work stop.
To position rear work stop:
1. Slide work stop adjustment assembly evenly
along support rods so rear work stop leading
edge is at approximate desired distance from
cutting edges of blades (see Figure 15).
Note: Move work stop assembly evenly on
both sides to keep it parallel with blades. Use
scales on top of support rods for approximate
positioning. Use fine ruler or tape measure
for precise positioning.
2. To keep rear work stop assemblies secured
in desired position, tighten knurled thumb-
screws (see Figure 15).
To adjust rear work stop assembly position:
1. Measure distance between cutting edge of
bed and leading edge of work stop. Compare
to scale measurement on each support rod.
2. If measurement does not match scale, loosen
cap screws securing support rods and adjust
each one until measurements match.
3. Re-tighten cap screws to secure support
rods.
2. With blade raised, loosen hex nut, then
rotate hold-down tension hex bolt (see
Figure 14) to raise/lower hold-down bar to
adjust clearance.
To adjust height of hold-down bar:
1. Remove blade guard.
3. Measure clearance between hold-down bar
and bed to ensure it is even side to side.
Adjust as necessary.
4. When clearance is even, tighten hex nut and
re-install blade guard.

Using Angle Cutting
Guide
Use the angle cutting guide as a side work stop to
cut a workpiece at an angle other than 90°.
To use angle cutting guide:
1. Calculate angle of cut and mark on workpiece.
2. Loosen adjustable lever on angle cutting
guide, use scale to set angle to match desired
cut, then tighten lever (see Figure 17).
3. Align workpiece with angle cutting guide and
position cut mark beneath blade to verify cut
angle.
4. Pull cutting lever to cut workpiece.
Adjusting 90° Guide
The 90° guide (see Figure 16) helps the operator
square the workpiece with the blades. To work
properly, it must be square with the blades.
Tools Needed Qty
Square ............................................................... 1
Hex Wrench 5mm .............................................. 1
To square 90° guide with upper blade:
1. Loosen (2) cap screws securing 90° guide.
2. Use cutting lever to fully lower blade.
3. Place square against hold-down bar and 90°
guide.
4. Keeping square even against hold-down bar,
adjust 90° guide so it is even against square,
then re-tighten cap screws on 90° guide to
secure setting.
5. Lift cutting lever to return blade to up position.
